Keyframed animation into path animation
Your demand sounds a bit strange considering the fact the BGE does not support paths.

You already have an animation. You can simply play it. To play rotation or location animations at different locations ensure the animating parts of the door are parented to a not animating object, such as a static empty.

Sample structure:


base (fixed)


frame (fixed)


wing left (animated)
wing right (animated)




You can align the door by moving and rotating the base object. (Indeed the frame can act as base too).
